IMPROVEMENT IN COVERS'-FOR BINS.

The Schedule referred to in these Letters atent and making part of the same.

To all whom 'it may concern `Beit `known that I, ALONZO S. MAXWELL, of Dixon, in the countyof Lee and State of Illinois, haveI invented'. a new and useful Improvement in Bin-Covers; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled'in the art to make and use the same, reference being had to the accompanying drawing forming part of this specification.

This -invention relates toimprovements in the bincovers made in the form of a segment of' a circle and moving in circular lines in opening and closing; and

It consists in the construction and arrangement of parts, as hereinafter described. l

The invention also consists in the application to the bins of casings to prevent the contents of the `bins working between the arms and the walls thereof;

also a packing to -exclude it from the space between the cover and the top` of .the case.

Figure 1 is a front elevation of a bin, the cover of which is arranged accordion to my improvements, and

Figure 2' is a transverse section ot' the sar-ne on the line a: :v of iig. 42. v

Similar letters ot' reference indicate corresponding parts.

A is the box or bin.

B, the segmental cover.

l -E represents the arms pivoted in the axis of. the

circle around which the cover swings at F.

These arms I provide with the curved heads or braces G, as long as the cover is wide, and I attach the cover'. thereto so as to be firmly braced at each side of the center, and these arms and bracesI make of metal, all in one piece, preferably castings.

To exclude the ou1, gronnd coffee, or other sub stance contained in the bin from' the cover, I provide the inner casings Hand the outer casings I, the same being arranged as shown, and for keeping it away from the arms' I provide the casing K, which in this example is only shown on one end; but in practice I propose to arrange similar casings at both ends.

Above the cover, anden the lower side of the casing I, I arrange a strip 'of cloth or other packing, L, for the more elieetnally excluding the dust and other line matters from the space.

A similar packing-strip may be arranged on the upper edge ot' the lower casing.

Having thus described my invention,

I claim as new and desire to secure byLetters Patenty The combination, with the case and the cover '13, provided with arms E and braces G, made .in one piece, ot' the casings H I K and packing-strips L, all as shown and described.

ALONZO S. MAXWELL.
